FRIEDRICH BURCKHARDT, OF ST. CHARLES, MlSSCURI.

PROCESS OF MANUFACTURING HOMINY, (EF-HTS, 34.0.

SPECIFICATION forming part of Letters Patent No. 313,952, dated-March 17, 1885.

Application tiled November 9, 18H3.

Charles and State of Missouri, have invented a certain new and useful Process ot` Manufacturing Hominy, Grits, Src., of' which the following is a full. clear, and exact description, reference beiughadtotheaccompanying drawings, forming part of this specification, and in which-- Figure 1 is a steamer for moist-ching the grain, part in elevation and part in vertical section. Fig. 2 is a steam-drier, part in elevation and part in vertical section. Fig. 3 is a side elevation ot a hulling apparatus. Fig. 4 is a vertical section of a cleaner or separator. Fig. 5 is an end elevation, part in seclion, ot'a kiln or air-drier. Fig. 6 is an end elevation, part in section, of a cooler. Fig. 7 is a vertical section of a polisher.

In Fig. 1, A represents an outer casing, Within which are conVeyer-tubes A', inclosing conveyer screws A2, driven or turned by means of a shaft, A3, with which they are connected by ruiter-wheels A".

A8 represents the pipe or spout through which the corn enters the apparatus, and A the spout through which it is discharged.

Aw represents the steamsupply pipe, and Au the pipe for the exhaust.

Alz represent passage-ways, forming conimunications between the opposite ends ot' the conveyer-tubes, so that the corn will be discharged from one into another. Openings in the tops ofthe conveyer-tubes are controlled by valves AM. The steam entering the top of the apparatus circulates through the tubes by means of these openings, heating the corn as it is conveyed from end to end of the tubes for the purpose of putting it in a condition to have the hulls removed. IVhen the corn has been steamed to inoisten it, it is next partlyV dried by passing it through a steam drying apparatus. (Shown in Fig. 2.) This appa- (No mnrlel.)

casing; I3', the conveyer-tnbes; B2, the conveyers, B3, the drivingshat't; B, the miterwheels; B5, the passages from one conveyertube to another; B, the grain-inlet pipe; B7, the graiu-discharge pipe or spout; BS, the steam-inlet pipe, and B the exhaust-pipe. After the grain has thus been partly dried it is passed through an apparatus to remove the hulls. Thishulling'apparatus is shown in Fi g. 3.

C represents hullers supported by posts C3 or other means. On the rop of each huller is a hopper, C4. After the grain has passed through'this hulling apparatus it is passed through a cleaner or separator. (Shown in Fig. 4.) It is next passed to a kiln or airdrier, which is represented in Fig. 5, and in which D represents an outer casing` within which are two series of conveyer-tubes, D', and screws D?, which are constructed and driven, and through which the grain passes, the saine as above described in connection with' the steamer.

D6 is the discharge'spout. A current of air is caused to pass through this apparatus from bottom to top, or vice versa, entering and escaping through openings D D1", and thus the grain is dried; but still being warm it is necessary to pass it through a cooler, which is represented in Fig. 6, and in which I repre` sents the outer casing inclosing` two series of conveyer-tubes, I, and screws I, which are also constructed similar to those of the steam apparatus, except the tubes are perforated, as shown, for the passage of air, which enters the casing and tubes through openings I3, being drawn in by'a suction-fan located in a chamber,

l9 is the discharge-spout.

The grain may be passed to a polisher, Fig. 7, after it leaves the cooler.

For more full description of parts of the apparatus herein shown, l would refer to the following applications tiled by me on the 31st December, 1883: No. 116,005, steamer; No. 116,006, steam-drier; No. 116,007, air-drier; No. 116,008, huller; No. 116,009, cooler.

I claim as my invention- 1. The herein-described process of manuacturing holniny, grits, 85e., which consists in steaming the gravin to moisten it, then drying it, then hnllng it, then Cleaning it, and then drying it by air-currents, as Set forth.

2. The hereiirdescribed process 0f manufacturing hominy, grits, Src., which Consists in steaming the grain to meisten it7 then dryingit, then hullingr it, then cleaning it, then drying it by air-enrrents, and finally cooling it, as set forth.
